Human-mediated lineage admixture in an expanding Ponto-Caspian crustacean species Paramysis lacustris created a novel genetic stock that now occupies European waters

Identifying the origins and colonization routes of alien species is critical to understanding the mechanisms, consequences and management of invasions. This study aims to demonstrate and explain conflicting genetic signals in a widespread invasive Ponto-Caspian mysid Paramysis lacustris using mitochondrial DNA and microsatellite markers. Native Black Sea populations of P. lacustris are divided into three distinct phylogeographic groups:...
